It’s basically an integrated bullets-counter in a magazine, and it’s available for most common service handguns on the market (SIG-Sauer, Beretta, Glock, CZ…). HK is not in the list, and I’m pretty sure people buying those kind of pistols would like this little gadget, and P220 Swiss military service pistol (I suppose because of the location of the magazine release).
It may be a solution to a non-existent problem, but it’s a very elegant and technical one. For those thinking around USD 200 for a magazine is steep, a new magazine from SIG costs around USD 120 those days.
I really hope they will amend trigger discipline in their presentation pictures. Via NR.
